RENGO is the largest trade union national center in Japan with 6.8 million membership

Japanese trade union organizations have a three-tier hierarchical structure enterprise-based unions, industrial federations, and the national center at the top. There is also a wide-ranging network, with local organizations, called “Local RENGOs,” set up in all of Japan’s prefectures.

The enterprise-based unions utilize negotiations and labor-management consultations in the workplace to improve working conditions, to monitor corporate activities, and to provide services to their members.
